Question

How will you test for the gas which is liberated when HCL reacts with an active metal ​

Answer 1

Answer:

Explanation:

Hydrogen gas is liberated when an active metal reacts with hydrochloric acid. For testing the presence of hydrogen gas, bring a burning candle near the mouth of the test tube in which the reaction is taking place. If the gas burns with a popping sound, then it can be concluded that it is hydrogen.

Answer 2

$\underline{\underline{\pink{\huge\sf Answer}}}$

☯ When HCL (Hydrochloric acid) reacts with an active metal (like zinc) it releases Hydrogen gas.To check of our observation is true let's pass the gas that is formed in the above reaction into a soap solution,so when we do so we may observe that there are some bubbles that start to escape out of the solution,and if this happens we may confirm it is Hydrogen because hydrogen is a lighter gas.

☯ Not just like that we can also test it by bringing a burning candle near the mouth of the test tube. So then we can observe that the gas burns with a pop sound so then we can conclude it is Hydrogen.

☯ An example for an active metal reacting with HCL will be, $\sf Ca+HCL \longrightarrow CaCl_2 + H_2$
